I just want some p0ints hope you find the answer
Answer:
30.5 cm
Step-by-step explanation:
0 < h ≤ 10 ⇔ Midpoint = 5
10 < h ≤ 20 ⇔ Midpoint = 15
20 < h ≤ 30 ⇔ Midpoint = 25
30 < h ≤ 40 ⇔ Midpoint = 35
40 < h ≤ 50 ⇔ Midpoint = 45
50 < h ≤ 60 ⇔ Midpoint = 55
<u>⇒ </u><u><em>Multiply each corresponding midpoint with it's frequency</em></u>
(5 × 1) + (15 × 4) + (25 × 7) + (35 × 2) + (45 × 3) + (55 × 3) = 610
<u>⇒ </u><u><em>Divide the total of 610 by the frequencies added together</em></u>
610 ÷ (1 + 4 + 7 + 2 + 3 + 3) = 610 ÷ 20 = 30.5
8x=20
x=2.5
To check
8(2.5)=20
Answer:
y = x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 2x + 2 ← is in slope- intercept form
with slope m = - 2
Given a line with slope m then the slope of a line perpendicular to it is
= - = - =
The line crosses the y- axis at (0, 1) ⇒ c = 1
y = x + 1 ← equation of line
To solve this you just have to isolate h
B=hm
Divide both sides by m to get h alone
B=hm
/m /m
B/m=h
